ISO 5660 ASTM E 1354 Cone Calorimeter
Introduction:
When a specimen is subjected to a conical heater, the cone calorimeter monitors the heat release rate (H.R.R.), smoke release, ignition duration, oxygen consumption, carbon monoxide and carbon dioxide generation, and mass loss rate. The Cone Calorimeter Test measures heat emission, ignition time, oxygen consumption, CO and CO2 generation, and flow of ignited gases as they are produced from test materials. The Cone Calorimeter Test is based on the theory that pure combustion calories are proportional to a necessary amount of oxygen for combustion and 13.1 MJ/kg is generated whenever oxygen 1kg is consumed.
Cone calorimeters are designed to allow for simple control of all components in a laboratory setting using a DAQ (Data Acquisition) program. Additionally, the 19" touch screen contributes to automatic testing and minimizes installation space.
Conical Heater 5 Step Heat Flux Controller is an optional component for research and development that aids in measuring the characteristics of combustion on specimens by temperature change and temperature increasing time after creating a simulated temperature of real fire conditions. This option makes it easier to measure various outcomes in a fire situation. With the 5 Step Heat Flux Controller, the user may easily set the user's temperature, rising pace, and duration after rising.
